SPECIFICATION forming part of Letters Patent No. 624,073, dated May 2, 1899.

Application filed October 12, 1897. $erial No. 654,997. (No model.)

To all whom, it nuty concern:

Be it known that we, JOHN L. MCSPADDEN and J oHN RAILTON, citizens of the United States, residing at Detour, in the county of Chippewa, State of Michigan, have invented a new and useful Stovepipe-Dam per, of which the following is a specification.

The special object of the invention is to make a Stovepipe-damper which will prevent soot from entering pipes above the damper, the unnecessary waste of fuel, and the usual escape of heat.

Figure 1 of the drawings is a perspective view giving an interior view when the damper has been closed; and Fig. 2, an elevation showing the damper open, so as to allow a maximum draft.

In the drawings, A A represent two plates,

pivoted together at the upper end, of sufficient width to fit snugly across the pipe-chamber B and each provided on the outside with a tube 0, open at the lower and closed at the upper end.

0 c are holes or openings through the plates and tubes for the inlet of smoke, the draft through them being regulated by a sliding valve D, while E is a Wire frame with a suitable handle e, by which the plates A A may be held more or less spread out at the bottom,

so as to form the interior chamber F and the exterior chamber G of the pipe-apartment B.

The smoke enters the interior chamber F, passes up and through holes 0 into the tubes 0, down these tubes and out at the lower end into the chamber G, whence it passes out at the upper end into the discharge-pipe.

The wire frame may be provided with spring and latch to secure it at any desired adjustment between the plates.

Having thus described all that is necessary to a full understanding of our invention, what we claim as new, and desire to protect by Letters Patent, is

The combination of a pipe, two plates piv- JOHN L. MCSPADDEN. JOHN RAILTON.
